System: NetBSD yui 1.3 NetBSD 1.3 (RFHPC) #24: Thu Feb 5 13:47:50 MET 1998 feyrer@jabberwocky:/usr/src/sys/arch/i386/compile/RFHPC i386


>Description:
	I'm just discovering something interresting in the "du" output of
	a 1.3/i386 system that mounts a disk via NFS from a Solaris 2.5
	machine:

yui% ls -la kdeutil*
-rw-r--r--  1 feyrer  bedienst  781936 Feb  1 15:39 kdeutils-Beta3-1.src.tar.gz
yui% du -sk kdeutil*
12416   kdeutils-Beta3-1.src.tar.gz

	On the Solaris box, this shows as:

rfhs8012% du -sk kdeutils-Beta3-1.src.tar.gz 
776     kdeutils-Beta3-1.src.tar.gz

The value given here seems to be off by a factor of 16. This problem
does not occur when mounting from another NetBSD box.


>How-To-Repeat:
	Put some file up on a filesystem exported from a Solaris 2.5
	box, then mount it and hand it to du. See it give a wrong value.

>Fix:
	Unknown.
